Application filed. September 2, 1904. Serial No. 223,131.

T all. whom it may concern:

as it known that I, \VILLIAM F. BEA'ION, a citizen ofthe .United States, residing at Friinkford, in the county of Philadelphia and State of lcnusdvauia. have invented certain new and useful Improvements in Explosive-Engmes, of whlch the follow-mg 1s a specification.

OU ectsof the present invention are to 0 providea compact, reliableand etficienti explosive engihe which may be used alone or arranged w th others of the same kind In a series, so as to economically provide for attaining an increasein horse power; to .so

construct and arrange the variousparts that they may be conveniently and comparatively inexpensively constructed and assembled; to arrange for the provision of a supply of clean mixture for a two-cycle operation; and enerally to provide a compact, durable and powerful engine which in use shall be both economical and reliable.

To these and other ends hereinafter set forth theinveution stated in general terms comprises the improvements to be presently described and finally claimed;

The nature, characteristic features and see e of the invention will be more fully un erstood from ,thb following description so taken in connect on with the accompanymg drawings forming pant'hereof and in which- Figure 1, is a view principally in central section of a cylinder and piston embodying features of the invention. Fig. 2, is a sec tional view taken on the line 2-2 etc iston. Fig. 3, is a vertical sectional view il ustrating a portion vof the cylinder Fig. 4, is a sectional view illustrating a pair of cyl- 40 ind'ers and pistons arranged to operate as a two-cycle engine, and Fig. 5, is a face view of a sparker.

Operations occur at each end of the cylinder andpiston so that the cylinders are made in two arts 1 and 2 in order that the pistons may no properly and conveniently placed within them. The parts 1 and 2 are shown as respectively flanged at their meeting ends, thus insuring accuracy of fit and there are lag bolts 3 (Fig. 3). which aiiord means for connecting these two parts. The parts of the cylinder are shown as provided with cavities 4 which constitute water jaclc ets. Connected with the pistons 5, which are shown as hollow so as to reduce their Weight, are rigid wrist pins 6 that project through slots 7 in the cylinders and afford means for connecting the links 8 which 013-. erateupon the crankst) carried by thedriving shaft 10, which is journaled inn base 11 "upon which may bcanounted and secured the required number of cylinders and pistons. At its ends the piston 5 is provided with papking 12. I v

' Referring more particularly to Fig. 1, 5 the proper explosive mixture is delivered from appropriate valve mechanism not shown, but which may be of any well understood type, into the opening or intake 13. Upon the descent of the piston 5','this mixture is compressed and passes by way pf the duct 1 1 which ranges lengthwise'au'd laterally of the piston and by way of the ll-shaped duct 15 formed in the cylinder wall to the upper cylinder. The guard to directs it away vfrom the exhaust 17, the piston then rises whereupon the mixture is exploded, driving it downward again per-Y mittin the exploded mixture to-escape by way 01 17 and compressing and taking in '80 new charge. Thus there is an explosion at every revolution. ()1? course the ductor passe e ll is closed from connnunication with he explosion chamber in every position of the piston, except its lowest position and since in its lowest position the packing rings 12 are on opposite sides of the inlet to the passage 15. there is no escape or leakage of the mixture. The exhaust leaves so rapidly by wayof the port 17, that the incoming 9o mixture traveling as it does under pressure isnot materially contaminated. Ina eneral sense the lower end of the cylinder ta res the place of and performs the function often performed by a crank case, but the mixture is not contaminated by the oil which is usually present in a crank case; thus there is secured a clean mixture and leakage is obviated.

The arran ement shown in Fig. 4;- in which two 0% the cylinders and their no.

cessories shown in Fig. 1 are employed,

obviously prz-duces two explosions for each revolution of the driving shaft 10v and they occur 180 apart. The described construction permits of the use of the sparking device which will now be described in connection, with Fig. 5a 18 is a base or support which is shownas attached to the side of the cylinder. Pivot-ed to this base are apair of contacts 19 and 20 connected respectively with the terminals of the contacts to normal position.

Cir

pivoted at one of its ends.

of a battery or other suitable source of current and Wilh'the coil and its accessories including a vibrator which are connected with the sparkin plug, the latter being properly placed, or example, in the openmg 21. The contact 20 is pivoted intermediate of its ends and the contact 19 is The spring 22 operating upon the shank of the contact 19 and the end of the contact 20, but being, of course, properly insulated, tends to turn these contacts up against their back stop 23 so as to hold the adjustable contact screw 24 in position for breaking the circuit. The link 8 is provided with an extension 25 which collides with the contact 20, turns both of the contacts 20 and 19, and brings the screw 2% into position for closing the circuit, which of course is interrupted as soon as the part 25 permits of the return To retard or advance the spark the angle of the base 18 is changed.

The base or support 11 is provided with pillow blocks for the shaft, with openings for the accommodationcf itscranks, and with suitable surface upon which one or more of the cylinders are secured, thus it is possible to conveniently duplicate the cylinders indefinitely and secure them to a sin le base and permit them to operate upon t e same shaft, thus affording convenient means for increasing the available horse power. Clearly the effect of the described arrangement is to produce, what is called, a well balanced engine, in that it receives power at frequent intervals.

The piston is relatively very long and the purpose of this is to cover the slots in the cylinder through which the wrist pin which is carried by the piston extends and in which it works. The lower end 01. this relatively long piston is closed so as to provide a comparatively small space between it and the lower end of the cylinder, within which comparatively small space compression takes place. The relatively long duct 14-, is provid ed to convey the compressed charge to the explosion end of the cylinder when the duct 14, registers with the lower inlet of the by-pass opening 15.

Itwill be obvious to those skilled in the art to which my invention relates that modifications may be made in details without departing from the spirit thereof, hence the invention is not limited further than the prior state of the 'art may require, but

- Having thus vdescribed the nature and objects of my invention what I claim as new and desire to secure by Letters Patent is' In combination at cylinder provided with an exhaust 17, communicating with its err-- tending longitudinally of the piston and opening through the lower head theeof and opening through the side wall of the same near the upper head, the by-pass 15, beingso located as to communicate with the upper end of the duct l hiand withthe explosion chamber when the piston is in its lowermost position, a. wrist pin connected with the iiston and working in said slots, a crank sha t provided with cranks and arranged outside oi the cylinder, andconnecting rods interposed between the wrist pin and cranks, substantially as described.

in testimony whereof I have hereunto signed my name.
